How to Reset the Ford PCM
by Zyon SilketThe power train control module on a Ford controls every aspect of the vehicle's engine, transmission, clutch and electrical and fuel delivery. Without a properly working PCM, the Ford will not run. At times, you may want to perform a reset of the Ford PCM for basic troubleshooting. This can often resolve small issues that you may experience with the Ford.
Step 1
Open the hood of the Ford. Loosen the lock nut located on the negative battery cable connector with a socket and ratchet. Pull the connector off the negative battery terminal.
Step 2
Wait for 20 minutes while the PCM bleeds off the electricity it stores for backup power. Once the power drains from the PCM, it resets.
Step 3
Slide the negative battery connector onto the battery terminal and tighten the lock nut with the socket and ratchet.
